Physic middle exam.

Last Wednesday, we had a big exam of Physic. We had 100 minutes to finish five problems of the exam. When I entered the meeting room for the exam, I felt very nerves. I didn't know how difficult the problem were, so I didn't have confidence getting a good grade to this subject. At the time that I should fight to Physic, I picked up my weapon--pencil and turned on the switch of my brain. After the exam I felt that I lost a lot of brain cells, it was too tired to have the test. Next all month, we will have many middle exam of every subjects. God bless me!
